Attach the Hozelock Indoor Threaded Tap Connector onto your indoor tap to connect your hose. Hozelock Indoor Threaded Tap Connector can be used on modern kitchen taps that have a built in aerator cartridge. This tap connector provides a secure method of temporarily attaching a Hozelock connector to a kitchen tap. Simple to use: remove the existing aerator cartridge from the end of the tap, and then screw in the new Hozelock cartridge. The new cartridge protrudes by an extra 8mm - there is a 3/4" bsp thread on the protrusion. Screw the Hozelock Indoor Threaded Tap Connector onto the 3/4" bsp thread when you want to connect the hose to the tap. Also included in the pack is a tap connector.
